* Sometimes, applications can put NULL chars into the screen-buffer

* FIXME - HACK: Improve the way we're doing that (i.e., put spaces
* instead of NULLs (or even, nothing) only if it exists a non-null
* char *after* those NULLs, before the end-of-line of the selection.
* Do the same concerning spaces -- i.e. trailing spaces --).
